Robert Lawlor sets out the system that determines the dimension and the form of both man-made and natural structures, from Gothic cathedrals to flowers, from music to the human body. By also involving the reader in practical experiments, he leads with ease from simple principles to a grasp of the logarithmic spiral, the Golden Proportion, the squaring of the circle and other ubiquitous ratios and proportions.Art and Imagination: These large-format, gloriously-illustrated paperbacks cover Eastern and Western religion and philosophy, including myth and magic, alchemy and astrology. The distinguished authors bring a wealth of knowledge, visionary thinking and accessible writing to each intriguing subject.

    The pictorial models are useful in understanding relationships. The models also abound in descriptive detail.

    Sachs is one of the world's most perceptive and original analysts of global development. In this major new work he presents a compelling and practical framework for how global citizens can use a holistic way forward to address the seemingly intractable worldwide problems of persistent extreme poverty, environmental degradation, and political-economic injustice: sustainable development.Sachs offers readers, students, activists, environmentalists, and policy makers the tools, metrics, and practical pathways they need to achieve Sustainable Development Goals. Far more than a rhetorical exercise, this book is designed to inform, inspire, and spur action. Based on Sachs's twelve years as director of the Earth Institute at Columbia University, his thirteen years advising the United Nations secretary-general on the Millennium Development Goals, and his recent presentation of these ideas in a popular online course, "The Age of Sustainable Development" is a landmark publication and clarion call for all who care about our planet and global justice.
